1) Excellent fireproof performance: The raw materials, production process and formula used for polyurethane double side sealing glass wool sandwich board make it have good fireproof performance. The test shows that it has a fire resistance of more than 1000 ℃. The polyurethane double side sealing glass wool sandwich board has passed the test of Italian authoritative testing agency GIOROANO S.P.A. According to the standards of the International Organization for Standardization (ISO), British BS and German DIN, the glass wool sandwich board meets the requirements of the fire protection standards M.I. 14/09/61 letter 91 and D.M. 30/11/83. The test results are as follows: 50mm thick polyurethane double side sealing glass wool sandwich board EI30, 80mm thick polyurethane double side sealing glass wool sandwich board REI 60100mm thick polyurethane double side sealing glass wool sandwich board REI 120.
2) Good thermal insulation performance: the thermal insulation performance of polyurethane double side sealing glass wool sandwich panel is based on the thermal conductivity of glass wool lambda= It is calculated based on 0.043 W/m2 K and the thickness of glass wool core material in corresponding proportion.
3) Remarkable sound insulation and absorption effect: polyurethane double side sealing glass wool sandwich panel has a significant reduction effect on noise transmission, especially suitable for places with designated flights. In addition, after the glass wool roof panel is used, the indoor sound caused by the impact of rain and hail on the roof steel plate of the building is also significantly reduced. Through the test, according to ISO717/82 and UNI 8270/7 standards, glass wool with a density of 120kg/m3 is selected as the core material, and the sound insulation effect can reach RW=29~30 dB. At the same time, the glass wool sandwich panel has excellent sound absorption effect, which can absorb the sound in a wide frequency range. According to ISO 354/85 standard, the sound absorption performance level of glass wool sandwich panel reaches DELTA LA=15.7 dB (A).
The polyurethane double side sealing glass wool sandwich panel gives full play to the unique performance of the glass wool core material, and has remarkable effects in fire prevention, heat insulation, sound absorption and sound insulation, etc; At the same time, the advantages of polyurethane such as plasticity, airtight, high strength and non water absorption are retained. The appearance of this material is a change in construction engineering, which fully integrates the advantages of polyurethane and glass wool and discards the shortcomings of traditional panels. In a sense, polyurethane double side sealing glass wool sandwich panel cannot be compared with ordinary glass wool sandwich panel.
